How to Fix 'unicodeescape' Codec Errors When Reading CSV Files in Python?

Dealing with Unicode Escape Decoding Errors in CSV Reading

When attempting to read a CSV file with Python, developers often encounter the following error:

SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated UXXXXXXXX escape

This error occurs when Python attempts to decode Unicode escape sequences in the CSV file, but the escape sequences are malformed or truncated. To resolve this issue, there are several effective solutions:

1. Using Raw Strings: Prefixing the path string with the letter 'r' converts it to a raw string, which ignores escape sequences:

data = open(r"C:\Users\miche\Documents\school\jaar2\MIK.6\vektis_agb_zorgverlener")

2. Using Forward Slashes in Path: Replacing backslashes with forward slashes eliminates the need for escape characters:

data = open("C:/Users/miche/Documents/school/jaar2/MIK/2.6/vektis_agb_zorgverlener")

3. Escaping Backslashes: To preserve the original path structure, escape each backslash with another backslash:

data = open("C:\Users\miche\Documents\school\jaar2\MIK\2.6\vektis_agb_zorgverlener")

By implementing these solutions, you can successfully read CSV files with specific path structures and resolve the unicode escape decoding error.
